Using contingent-claims valuation, we introduce novel hedge ratios for credit exposures using put options. Option hedge ratios are generally in line with the empirical sensitivities of credit spread changes to put option returns and, relative to stock hedge ratios, produce further reductions in volatility for a portfolio of North American firms. We show that option hedge ratios capture option-specific credit exposure related to the VIX index and the default spread, which is unaccounted for by Merton’s (1974) equity hedge ratios alone. Combining stocks and put options for credit risk hedging can be done effectively using the volatility smirk.

We find that managers receive more risk-taking incentives in their compensation packages once their firms are referenced by credit default swap (CDS) trading, particularly when institutional ownership is high and when firms are in financial distress. These findings provide suggestive evidence that boards offer pay packages that encourage greater risk taking to take advantage of the reduced creditor monitoring after CDS introduction. Further, we show that the onset of CDS trading attenuates the effect of vega on leverage, consistent with the threat of exacting creditors restraining managerial risk appetite.
